METHOD AND A DEVICE FOR FINDING IMPERFECTIONS IN AN RF PATH
First Claim
1. A method for finding differences in path loss between a plurality of radio frequency (RF) paths between a first transceiver and a second transceiver in a wireless communications system, the method comprising:
- using, during defined intervals of time, only one RF path to transmit from one of said transceivers to the other of said transceivers,measuring a strength of a signal received during at least a number of said intervals,comparing the signal strength and path loss between different RF paths, andfinding imperfections in one or more of said RF paths based on the comparing.

Abstract
The invention discloses a method (700) for finding differences in path loss between a plurality of RF paths between a first (120, 130) and a second (120, 130) transceiver in a wireless communications system (100). During defined 5 intervals of time (SACCH1-SACCH4), only one RF path is used to transmit from one of said transceivers to the other of said transceivers, and the receiving transceiver measures the strength of the signal received during at least a number of said intervals, thus making it possible to compare signal strength and thereby path loss between different RF paths, which in turn 10 makes it possible to find imperfections in one or more of said RF paths.

15. A transceiver for use in a wireless communications system, the transceiver comprising:
-
at least a first transmitter and a second transmitter, and at least a first receiver and a second receiver, the at least the first transmitter and the second transmitter and the at least the first receiver and the second receiver being for communication with another transceiver in said wireless communications system, so that at least a first radio frequency (RF) path and a second RF path are available, in both the transmit and receive direction for said transceiver, for communication with a second transceiver in the wireless communications system, where the transceiver further comprises; means for switching between the first and second RF paths so that during defined intervals of time, only one RF path, of the first and second RF paths, is used for transmission or reception in the communication with said second transceiver in the wireless communications system. - View Dependent Claims (16, 17, 18, 19)
